The diagonal of a square is x what is the perimeter of the square

RSB [31]

Answer:

2 $\sqrt{2}$ x

Step-by-step explanation:

The diagonal divides the square into 2 right angles with legs s and hypotenuse x

Using Pythagoras' identity on one of the right triangles, then

s² + s² = x²

2s² = x² ( divide both sides by 2 )

s² = $\frac{x^2}{2}$ ( take the square root of both sides )

s = $\sqrt{\frac{x^2}{2} }$ = $\frac{x}{\sqrt{2} }$

Thus

perimeter = 4s = 4 × $\frac{x}{\sqrt{2} }$ = $\frac{4x}{\sqrt{2} }$

Multiply numerator/ denominator by $\sqrt{2}$

perimeter = $\frac{4x\sqrt{2} }{2}$ = 2 $\sqrt{2}$ x

I need help to answer/ solve this

Neporo4naja [7]

Answer:

${x,y}={6,-1}$

Step-by-step explanation:

Solve by Substitution :

// Solve equation [2] for the variable y

[2] y = -x + 5

// Plug this in for variable y in equation [1]

[1] x - 2•(-x +5) = 8

[1] 3x = 18

// Solve equation [1] for the variable x

[1] 3x = 18

[1] x = 6

// By now we know this much :

x = 6

y = -x+5

// Use the x value to solve for y

y = -(6)+5 = -1

Solution :

${x,y} = {6,-1}$

The radius of the cone is 1.25 inches, and its height is 2.75 inches. If the diameter of the bubble gum ball is 0.5 inches, what

nasty-shy [4]

<h2>Explanation:</h2><h2></h2>

The volume of a cone can be found as:

$V=\frac{1}{3}\pi r^2 h \\ \\ \\ Where: \\ \\ V:Volume \\ \\ r:radius \ of \ base \\ \\ h:height$

Given the radius and height, we can find the volume of the cone:

$V=\frac{1}{3}\pi r^2 h \\ \\ V=\frac{1}{3}\pi (1.25)^2(2.75) \\ \\ V=\frac{1}{3}\pi(1.5625)(2.75) \\ \\ V\approx 4.5in^3$

The volume of a sphere is:

$V=\frac{4}{3}\pi r^3 \\ \\ \text{Each gum ball has a diameter of 0.5in, so the radius is:} \\ \\ r=\frac{0.5}{2}=0.25in$

So, for each gum ball the volume is:

$V=\frac{4}{3}\pi r^3 \\ \\ V=\frac{4}{3}\pi (0.25)^3 \\ \\ V=0.065in^3$

Therefore, the he closest approximation of the volume of the cone that can be filled with flavored ice is:

$4.5-0.065=4.43in^3$

Conclusion: The volume of the cone that can be filled with flavored ice is 4.43 cubic inches.
